In this lab assignment, using polymorphism. Starting with create a class Bank , this will be the base class in this project. The private data of this class will be vector of bank accounts. Each bank account will contain the account number (random 4digit integer), account type (saving or checking), and balance of the account. The base class and Account can be declared as suggested in the follows:

enum account_type {saving, checking} class Account { public: Account () ~Account() private: int account_number account_type type double balance }

class Bank { public: Bank() ~Bank() // additional functions as needed virtual void deposit() = 0 virtual void withdraw() = 0 private: vector bank_accounts }

Create 2 other derived classes from the base class called Saving and Checking. Redefine the deposit and withdraw functions for each class as follow:

For Saving class when call deposit function, a new amount (can be zero) will be added to the current balance along with the interest from the original balance when call withdraw function, check if the amount is valid (cannot exceed the current balance)

For Checking class when call deposit function, a new amount (cannot be zero) will be added to the current balance a transaction fee will be subtracted from the balance. when call withdraw function, check if the amount is valid (cannot exceed the current balance minus the transaction fee) withdraw the amount and subtract the transaction fee from the balance. When making the bank accounts, the account numbers will be the random 4digit integers the initial balances will be the random double value between $0 and $100.00 the account type will be either saving or checking.

The interest rate will be 0.01 for all saving accounts. The transaction rate will be $0.50 for all checking account. Start the program by making 5 random accounts. The following is the sample inputs and outputs
